Start with the product’s actual tasks, typography, colors, content, and accessibility requirements. Name who can change these decisions and how engineering and design stay aligned. ## Evaluate real tasks An illustrative operational form needs labels, validation, keyboard focus, and a clear recovery path for unsuccessful submissions. Evaluate the component inside realistic workflows, narrow screens, and both themes. The [WCAG guidance](https://www.w3.org/TR/WCAG22/) provides accessibility requirements to assess; a component library does not establish conformance by itself. ## Maintain the system Document contribution, review, release compatibility, and adoption support. Track meaningful defects and user feedback instead of treating package downloads as proof of quality. Reuse should help teams preserve correct behavior while keeping each product’s specific needs understandable. ## Key takeaways 1. A design system records reusable interface behavior and the decisions that keep it consistent. Start with the product’s actual tasks, typography, colors, content, and accessibility requirements. Name who can change these decisions and how engineering and design stay aligned. - Perspective - Experience Design Written by ## Quantlix Editorial Insights team · Quantlix [Talk toQuantlix](https://quantlix.com/en/contact/) [More blog](https://quantlix.com/en/blog/) ## Related blog [More blog](https://quantlix.com/en/blog/) - ![Circuit traces forming a human head on a blue background](https://quantlix.com/_astro/artificial-intelligence.z-Hurd7C_Z2l7A16.webp) Playbook Industrial AI Oct 8, 2026 (2026-10-08) ### [How to choose an industrial AI partner](https://quantlix.com/en/blog/choose-industrial-ai-partner/) Compare industrial AI partners by workflow expertise, integration design, evaluation evidence, human control, and support.
